The Virginia Anti-Shariah Task Force is an activist organization that also opposed establishment of an Islamic school in northern Virginia.

Task force chairman James Lafferty said at a news conference Monday that last week's burial of Tamerlan Tsarnaev in a private Muslim cemetery in Caroline County was "an awful sneak attack on the people of Virginia."

Lafferty says federal officials should investigate whether any laws were broken. Local and state officials already are doing so.

Lafferty predicted the site will become a shrine for Islamic jihadists. The group that helped facilitate the burial says it will not allow construction of any sort of monument or shrine.
